Gate News message, April 17 — OpenAI announced that ChatGPT now supports HWP and HWPX file formats used by Hancom Office, the leading Korean office suite. This development allows domestic users to upload Korean-language documents directly without format conversion, enabling them to analyze and extract information through natural language queries.
Google’s Gemini 3.0 previously added HWP support, followed by ChatGPT’s announcement today. The move addresses a long-standing limitation where HWP documents were considered incompatible with global AI tools. OpenAI stated it aims to expand ChatGPT’s usability within the Korean user environment and plans to continue improving features based on local business needs and workflows.
The development carries significant implications for public and corporate sectors in South Korea that handle extensive administrative documents. Users can now summarize key content, extract information, and analyze HWP files directly within ChatGPT without technical barriers.
Market analysts view this as a major catalyst for Hancom’s stock recovery. The company’s shares have declined over 8% in the past three months amid foreign selling pressure. Industry observers believe that global AI ecosystem integration could accelerate Hancom’s B2B revenue expansion, particularly through its AI-based data loader solutions, as the “Galapagos specification” undervaluation factor diminishes.
